PostgreSQL is a sophisticated relational database administration system, that you can use on many platforms (UNIX, Linux, FreeBSD, OpenSolaris, Windows) and with various scripting languages (Perl, PHP, Python, Java, Ruby). Since it's open-source, it can be effortlessly modified to fit the demands of any developer who employs it. PostgreSQL is also amongst the the most dependable and stable database systems, with significantly better performance in managing complicated procedures when compared with similar systems. It's ideal for large-scale apps as a single PostgreSQL database doesn't have a limit for the size, while an individual table may be up to 32 Gigabytes. It is not surprising that many business, academic and governmental entities are already employing PostgreSQL - Skype, the University of California, Berkeley and the US Department of Labor being a few examples.
